Abstract
A composite rim for a bicycle wheel generally includes a radially outer tire-engaging portion, a radially inner spoke-engaging portion and first and second sidewalls. The second sidewall is spaced apart from the first sidewall. The first and second sidewalls extend between the tire engaging and spoke-engaging portions. The rim includes at least one through-hole and a pattern of through-thickness stitching reinforcement at the through-hole. The tire-engaging and spoke-engaging portions and first and second sidewalls form a toroid.
